BED-PLATE.

Application filed August 2, 1913. Serial Ilia-782,748.

' To all whom it may camera:

, motors.

Be it known that I, CHESTER B. MILLS, a citizen of the United States, and a resident of East MeKeespoi-t, in the county of Alleghenyand State of Pennsylvania, have invented a new and useful Improvement in Bed-Plates, of which the following is a specification.

My invention relates to bed plates such as are employed in connection with electric motors or other. power devices, and it has for its object to provide a means for mounting motors which is simple and inexpensive in construction and convenient in operation to adjust and maintain the position of the In the adjustment of the positions of motors by means of bed plates having movable portions to which the motors are attached, it has usually been necessary to loosen binding screws or similar devices before adjustment and to tighten thesame ance with my invention.

after adjustment.

I have provided a structure by means of which-the position of amotor may be adjusted without either preliminary or subsequent operations. The movable portion of the bed plate comprises a resilient plate member, the tension of which may be adjusted as desired and which will be retained- 1n any position in which it may be placed.

The details of my invention will be described in connection with the accompanying drawings in which Figure 1 is a plan view of a bed plate constructed in accord- Fig. 2 is a side view, partially in section and partially in elevation, of the bed plate with a motor attached thereto. Figs. 3 and 4 are sectional views taken on lines TIL-III and IVIV, respectively, of Fig. 1.

The bed plate 1 comprises aystationary base member 2 of cast or pressed material which is provided with holes 3 for fastening bolts and with a threaded lug 4: to receive an adjusting screw 5. A .resilient plate member 6 1s slidably mounted upon the member 2 and is attached to the latter by means of bolts 7 which pass through slots 8 in the plate .6. The plate 6 is curved with its convex surface outward and its side portions 9 engage bearing surfaces 10 on the base member 2. The plate 6 is provided at one end with a bent portion 11 having an opening 12 to receive a reduced portion 13 of the adjusting screw 5. p as attached to'the plate member 6 by bolts A motor 1 1 is illustrated 15 which project through slots 16 in the plate 6 and into slots 17 in the member 2. The motor 14 is illustrated as an electric motor of small power'and is provided with Patented May 2'2, 191:.

a drive pulley" 18 for belt connection to suitsuring a uniform degree of friction between the plate member .6 and the member 2 at their respective engaging surfaces. The path of movement of the plate member .6 is controlled by the bolts 7 and the slots 8. The alinement of the bolts 7, slots 8 and the adjusting screw 5 providesa simple means for preventing the binding of the various parts during the operations of adjustment.

The plate member 6 and the motor 14 will be retained in their various adjusted positions by the adjusting screw 5. The tension of the plate member 6- prevents any vibration of the motor relatively to the base 2.

I claim as my invention:

j 1. The combination with a stationary member, of a relatively movable resilient member mounted thereon and in adjustable frictional engagement therewith, and means for adjusting the relative positions of said members. r

2. The combination with a stationary member, of an inherently resilient plate member in frictional engagement therewith, and means coacting with said stationary member for shifting the plate member.

3. The com ination with a stationary member, of a resilient plate member in frietional engagement therewith, and means co acting with said stationary member for adjustin the tension of said plate member, where y the degree of said frictional engagement may be varied.

- 4. The comblnatl'on with a stationary means for adjusting m i ageaaaee the tension of said plate inembenand means for shifting said plate member.

5. The combination with a stationary base member of a resilient plate member slidably mounted thereon, means for adjusting the tension of said plate member, means for shifting said plate member, and means alined with said shifting means for guiding the movements ofsaid plate member.

6. The combination with a stationary base member, of a resilient member slidably mounted thereon, means for adjusting the tension of said slldable member, and means plate "member, and means-alined wit for adjusting the position of said slidable member.

7. The combination with a stationary member, of a resilient plate member slidably mounted thereon, means for shiftin said said of said plate member. 4

8. The combination -with a stationary member, of a relatively movable member having portions thereof in adjustable fricmember and means for adjusting the relative' ositions of said' members.

9. he combination with a mtionary member, of a relatively movable member having portions thereof in frictional engagement with the said stationary member and means coacting with said stationary member for varying the degree of said frictlonal engagement.

10. The combination with a stationary member, of a curved resilient plate having parallel edges thereof in frictionaLengagement with the said stationary member and means coacting with said .statlonary member for varying the degree of said frictional engagement.

In testimony whereof I have hereunto-subscribed my name this th day of July, 1913.
